Answer:
yes! i love it and would have to be litteraly every wells they are halarious
Explanation:
The correct diagram is C.
In fact, the magnetic force works as the electrostatic force: like poles repel each other, while opposite poles attract each other. In this example, we have two magnets one next to each other, and we see that the north pole of one magnet is close to the south pole of the other: therefore, the two poles attract each other, so the two magnets will move closer, as in diagram C.
d = distance between the two point charges = 60 cm = 0.60 m
r = distance of the location of point "a" where the electric field is zero from charge 
between the two charges.
= magnitude of charge on one charge
= magnitude of charge on other charge
= 3
= Electric field by charge at point "a"
= Electric field by charge at point "a"
Electric field by charge at point "a" is given as
= k /r²
Electric field by charge at point "a" is given as
= k /(d-r)²
For the electric field to be zero at point "a"
=
k /(d-r)² = k /r²
/(d-r)² = 3 /r²
1/(0.60 - r)² = 3 /r²
r = 0.38 m
r = 38 cm
Roughly 5.6 meters per second (m/s)
Velocity is determined by distance divided by time. In this case, we divide 50 meters by 9 seconds, giving us the dog’s velocity of 5.55555 (repeating) meters per second. We can round to 5.6 m/s if needed.
